                ### 🔍 Fallacy Detection Model
                - **Architecture:** DistilBERT-based classification
                - **Training:** 3,200 carefully curated examples across 16 fallacy types
                - **Performance:** 100% accuracy on test set with high confidence scores
                - **Detects:** Logical errors, rhetorical manipulation, and argumentative fallacies
                
                ### 🎭 Intent Detection Model  
                - **Architecture:** Multi-label DistilBERT with custom classification head
                - **Training:** 1,226 examples with multi-label annotations
                - **Performance:** F1-score of 0.77 macro average (excellent for multi-label)
                - **Detects:** Psychological intentions and communication motivations
                
                ### 💭 Combined Analysis

                - **Deeper insights** into communication patterns
                - **Context-aware interpretation** of fallacies within intent frameworks
                - **Actionable suggestions** for more effective communication
                - **Understanding of WHY** people communicate in certain ways
                
                ### 📊 Performance Highlights
                - **Fallacy Detection:** 100% accuracy, 98%+ average confidence
                - **Intent Detection:** F1-scores from 0.85-0.99 per category
                - **Combined Analysis:** Novel psychological insights from model intersection
                
                ### 🎯 Applications
                - **Personal:** Improve relationship communication
